DBFTfDEFLECTR FOR WINDOWS.

Application filed January 31, 1925. Serial No. 6,093.

@ZZ iii/iosa it may; eminem 3e it known that we, JAMES B. LAMON'C lniNfiNn A; Lonnbz, citizens ci the lfniied `etates, and residents of thecity and county et' San Frai'icisco, and State of Caliornia, haveinvented certain new and use- 'iul Improvements in Draft Delectors forllindows, of which the following is a speciiication. j

This invention relates toV draft detlectorsy for windows, and isparticularly adaptable to the ordinary double-sash windows most commonlyused, though it may be used to advantage with some types of reversiblewindo Our invention comprises a pair of suitable 'frames carrying panesand adapted to be icld in sl'lable relationship by means otl fuidewaysborne by one or the other of the iframes, permitting` a sliding iitadmitting` oi' a telescopic movement in adjusting for dit ferent widthwindows.v These-trames are adapted to carry end brackets which formsupports of tiangular shape adapted to tit between the easement uprightsand securelyr hold the frames in position by means of slots engagingscrews, or the like, borne by the upright-s. Vfhen in position, thebottoms of the frames rest upon the window sill and the brackets supportthe frames at the proper inclination within the room to deflect enteringair currents upwardly into the room, w ien the lower window sash hasbeen raised a required distance above the window sill. The frames may beconstructed of metal, or ot' wood, or anywvell known fibre-board, orother material adapted to carry window panes oit' transparent,translucent, opaque, or other character.

A primary object of my invention isV to proif'ide a draft delector olthe type desir;- nated ot simple design, cheaply const-ructei'l. and ofa character that may be easily and readily placed in positionandadjusted to width without resorting to cutting or iii/ting'.

A further object is to provide a construction in draft deliectors thatis not alone adjustable as to width, but, also, as to height and itsinclination to entering` air currents.

The invention is fully illustrated in the accompanying drawings, inwhich:

Figure 1 is a vertical sectional. view of an"M ordinary window Casement,showing our invention inplace and restingin inclined position upon thewindow-sill, with the lower sash raised slightly above the sill for theadnnsion of fresh air;

l*l c re 2 is aside elevation, showing the device'as it would appearremoved 'from the window easement, with its frames in telescopedrelationship;

Figure 3 isv a top plan view, as shown in Figure 1 and indicated by thearrow in that ligure; and

Figure et is a perspective view, showing` tlie'irames in extendedrelationship, or, as they would appear when in readiness for insertionbetween members. y, i

Yleierringg" nore particularly to the drawour invention is comprised ofapair .mallframes 1 and 2, in the forni of miniature window frames,adapted to carry window panes 3 and 4, the frame end-pieces 5 and 6being oiiset with relation to their respective connecting pieces, sothat they may lie in a common plane in either telescoped or extendedposition.

The frames 1 and 2 are adapted toslide one upon the other, with the'frame 2 pro` vided with channelled guideways 7 and 8 secured to itsupper and loweredges by means of screws, or the like, 9 and 10, andadapted to receive the frame 1, as shown in Figures 1 and 4; .triangularbrackets 1l and 12 are respectively secured to the frame endpieces 5 and6 of the frames 1 and v), by means of nails, or the like, 13, andVextend at right angles to said frames and are provided at their outeredges with obliquelv arranged attaching` slots 141 and 15 adapted toengage screws, or the like, 16, placed at predetermined positions'vuponthe inner faces of the easement nprig'hts 17. ,A small the easement'ksidepin 18, or the like stop` may be placed on the inside of the innerend-piece ot the trame 1,

after theV trames have been assembled, and in position to engage theinner edge of the inner end-piece of the frame 2, to prevent the frames,at any time, being' pulled en-` vin the direction indicated by thearrows,'thiis obviating1 the direct currents or horizontally directeddrafts, so vexatiously annoying in oifioes in scattering papers anddoeuinents, in addition to being prolific agents in causing congestions,colds, and other ailments.

rfhe inclination of the deflective surface may be varied, or adjusted,to any desired angle of inclination, by simply varying the shape el theend brackets 11 and 12, or the position and direction ot the: slots 11and 15 relative to the attaching screws 16.

The device is intended to rest snugly upon the sill 19', to forni anair-tight tit bet-Ween the. frames 1 and 2 and said sill, and the lowersash of the Window should not, ordinarily, be raised above the positionshown in the drawings-that is, relative to the top edge of thedeflee-tor.

Y he inyentions predominating features are. its adaptability to anyordinary Window; its extensibility, permitting adjustment laterally totit it to- Windows-of varying Widths; and its simplicity and the easewith vwhich it may be attached to any WindowI` easement.

Haring thus illustrated and described our invention in its preferredform, we elaini, and desire to secure by Letters Patent:

In a ldevice of the character described, comprising, in combination witha Window easement, attaching-screws mounted in the Casement traine, anda pair of slidable frames carrying window` panes, said framescoinprising` end pieces and connecting pieces, triangular end bracketscarried by the outer end pieces, said outer end pieces being offset Withrespect to their respective connecting pieces and thereby adapted to liein a coininon plane When teleseoped or extended, one et" saidV framesbeing provided With chair nelled guide-Ways secured to its upper andlower edges to receive the other of said trainee, one of said framesbeing provided with a stop-pin adapted to extend into the path of theend-piece of the other trarne to liinit the inoveinent of said framesrelative to each other, said triangular brackets being provided at theirupper edges With obliquely arranged slots open at their outer ends andadapted for adjustable enga-gement Withsaid attaching-screws.
